hey guys... since its kinda on the nv3500
i have a quick question not to whore but just hate starting new threads cause there are soo many dumb ones..

anyways,....

going from a nv3500 s-series to a 73 tubor 350.. will my truck be screaming with 2:73's in the ass end? just got the t350 off ebay for 22 bucks...and it works.. prety much so the wife can drive the dime...

I know this is a really old thread but I have a question on this subject. I have a 90 S10 Blazer 4x4 2dr with the original NV3500 and the crappy 4.02 1st gear. It was mentioned that the newer NV3500 has a 3.48 1st. My question is, what model do I need to look for to get the newer trans with the 3.48 1st ? My Blazer is more street oriented so that is the reason.
